Spraying Honeyberry Plants

Familiarize yourself with potential pest and diseases issues for honeyberry plants in your area. Your local cooperative horticultural extension is an excellent resource for this information. Documents for identification and control (put together by your local state universities) may already exist online, free of charge. Your nearest independent garden centers and local growers are also invaluable sources of pest and disease control in your area.

Prior to using any sprays, be sure to read and follow the instructions printed on the product label. Due to the potential for sensitivities that may vary from plant to plant, always test a small area prior to making a broad application.

NOTE: This is part 9 in a series of 11 articles. For a complete background on how to grow honeyberry plants, we recommend starting from the beginning.

Honeyberry plants are not known to have significant insect pests or disease issues to spray for, so spraying honeyberry plants may not be necessary at all; however, here are some things to keep in mind if you find that you need to spray your honeyberry plants.

General Maintenance

Before you begin, read and follow all instructions on the labels of the products you have in hand. Do not combine any chemicals unless the labels on each chemical spray involved specifically state that you can safely do so.

A proactive home spray program for honeyberry plants includes dormant-season as well as growing-season sprays for pests and diseases. Research your location and learn about any pests or disease that are common in your area. If you know certain diseases are common in there, consider planting disease-resistant varieties if possible.

Note: Contact your local county Cooperative Extension for alternative suggestions and advice on cultural and chemical control methods if certain sprays offered by Stark Bro’s are not recommended for use in your area.

When to Spray Honeyberry Plants
  • Growing Season – Bud Break (emergence of new growth)
  • Growing Season – After Blossom (after petals drop*)

*gives bees and other beneficials a chance to safely pollinate the blossoms

It bears repeating: Always follow instructions printed on container label for more detailed information, such as timing and application instructions specifically for honeyberry plants.
